Transcript

  • 1. The relief model<br />
  • 2. IndexKinds of relief model<br />Fluvial model (rivers)<br />Torrential model (torrents)<br />Glacier model (glacier)<br />Karstic model (subterranean water)<br />Litoral model (swell) <br />Eolic model (wind)<br />
  • 3. Fluvial model<br />Form narrow pass, flood plains and wave-cut platform. This areas are very goods for the farming and the human occupation. <br />Form valleys with “V”<br />In Spain this kind of erosion is very frequent.<br />
  • 4. Fluvial model<br />Narrow pass river Cares (Picos de Europa)<br />
  • 5. Fluvial model<br />Flood plains (River Pas and Narcea)<br />
  • 6. Fluvial model<br />Wave-cut platform (River Cinca)<br />
  • 7. Fluvial model<br />Meanders of a river (Valle en artesa)<br />
  • 8. Fluvial model<br />Valley with form “V”<br />
  • 9. Torrential model<br />It type of relief model is very erosive and origin beautiful landscapes. <br />Origin relieves like canyons and carcavas.<br />When are accumulated the erode materials form alluvial fans erosions.<br />They aren´t good areas for the population and farming. <br />
  • 10. Torrential model<br /> Carcavas Tabernas desert (Almería)<br />
  • 11. Torrential model<br />Almadenes Canyon (Cieza) Río Lobos Canyon (Soria)<br />
  • 12. Torrential model<br />Waterfalls and rapids. They are very frequents in high mountains.<br />
  • 13. Torrential model<br />Ravines and narrow pass. The aggressive erosion origin for the water and the materials that the water bring, form the ravines. <br />
  • 14. Glacier model<br />This kind of model is origin in high mountains areas, very colds zones.<br />The human occupation is very small and this areas normally are touristic.<br />The glacier valley has got “U” form and it has got quite population. <br />Form glacier cirques and other forms.<br />
  • 15. Glacier model<br />Glacier cirques. Origin for the accumulation of ice.<br />
  • 16. Glacier model<br />“U” form valley origin form the weight of the block of ice.<br />
  • 17. Glacier model<br />Glacier erosion. <br />
  • 18. Glacier model<br />Kinds of erosion in the glacier model. <br /> Glacier spite, morren and glacier cirque.<br />
  • 19. Glacier model<br />
  • 20. Glacier model<br />
  • 21. Glacier model<br />Glacier lake. Typical in post-glacier landscape<br />
  • 22. Glacier model<br />Erosion in rocks. The water infiltrate in the rocks, and when is freeze, this water occupy more, and the rock is broken. <br />
  • 23. Karstic model<br />In areas forms for limestone or plaster, the water infiltrate in crack, and it dissolving the rock and form galleries and caverns.<br />There are two types:<br /> - Superficial: origin form the dissolution and the roof of the cavity like dolines.<br /> - Subterranean. <br />
  • 24. Karstic model<br />Galleries and caverns<br />
  • 25. Karstic model<br />When the water is infiltrate can produce stalactites and stalagmite for the calcium carbonate dissolved in the water. <br />
  • 26. Karstic model<br />Dolines. <br />
  • 27. Littoral model<br />The swell is an agent very erosive. <br />When the swell is more aggressive form cliffs, capes and ledges.<br />When the swell is not very aggressive form beaches, the place where the eroded materials are accumulated. <br />When the cliffs are eroded form abrasion platforms. <br />
  • 28. Littoral model<br />Cliffs. Platform abrasion. <br />
  • 29. Littoral model<br />Cliffs. Platform abrasion.<br />
  • 30. Littoral model <br />Formation of cliffs.<br />
  • 31. Littoral model<br />When there is a cliff can origin arches.<br />
  • 32. Littoral model<br />In the littoral model can origin beaches, tombolos and arrows.<br />
  • 33. Littoral model<br />Littoral lakes. <br />
  • 34. Eolic model<br />In Spain this model is not very important, but the wind transport the sand accumulated in the beaches, origin coastal dunes.<br />Is predominant in deserted zones. <br />When the wind carry the sand and the clay form rocky deserts. <br />When there are sedimentation of sand, is origin dunes field. <br />
  • 35. Eolic model<br />The particles in the wind origin corrosion in rocks so the rocks have got different shapes.<br />
  • 36. Eolic model<br />Rocky deserts.<br />
  • 37. Eolic model<br />Dunes fields. <br />
  • 38. The end<br /> Ana BelénAgarrabeitiaCasado 3B<br />
